CARBURETOR.

SPECIFICATION forming part of Letters Patent No. 484,949, dated October 25, 1892.

Application filed February 4, 1892. Serial No. 420,261. (No model.)

To aZZ whom it may concern:

Be it known that I, JOHN CLINGMAN, a citizen of the United States, residing at Dayton, 1n the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Carburetors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to carburetors; and it consists of certain novel useful featuresof construction of the same, fully disclosed in the accompanying drawings and the specification following, and more particularly pointed out in the claims.

In the drawings, Figure 1 represents a sectional view of the reservoir and carburetor.

2 is a sectional view of my improved dev1ce for operating the cut-off valve located between the reservoir and carburetor. Fig. 3 is a similar view of a pipe-holding device, and Fig. 4 represents a modification of the latter.

Similar letters of reference indicate identical parts throughout.

The carburetor consists, preferably, of a main outer casing A and a smallercasing l3, placed within the same in such a manner as to allow a space to intervene between the sides and tops of the casings, which space forms the carbureted-air chamber A. The casing Bis divided by a plate b into two compartments E and B which form, respectively, the air and fluid chambers of the carburetor. A deflector O is provided at or near the top of the air-chamber E, which is substantially of the form shown in the drawings and consists, preferably, of a hollow perforated disk into which air is forced from a suitable air-forcing device through the inlet-pipe c and passing through the perforations is evenly distributed through the air-chamber and any uneven pressure at one point avoided. The deflector may, however, comprise a plain disk, placed below the vent of thepipec, against which the air is discharged and distributed through the chamber. The plate I), which forms the bottom of the air-chamber, is provided with a number of tubes f f, which-open from the air-chamber and extend downwardly chamber B, which is maintained at a given point, as hereinafter described.

The sides of the chamber B are provided with perforations (1 just below'the plate 1), opening into the gas-chamber. The air in process of carbureting is forced from the airforcing device through the pipe 0 against the deflector O and fills the air-chamber E. Passing from the air-chamber through the downwardly-projecting pipes f f, it is discharged, preferably, below the surface of the carbuoughly carbureted, escapes through the openings cl into the gas-chamber. It will be seen that the air between the plate b and the top of the chamber E forms a cushion, which receives the force of the incoming air passing from the deflector and serves to prevent irregularity of pressure. It will also be observed that no carbureted air can escape through the air-chamber and blower, which frequently happens in other machines, as it is obvious that it is practically impossible for the carbureted air to force its way down through the fluid and upward through the pipesff- The caroureting fluid is supplied to the chamber B automatically, and the supply is governed by the pipe 6, one end of which opens into the chamber B at a point even with the normal surface of the fluid insaid chamber'and the opposite end is connected with the reservoir D, near the top of same. The carbureting fluid enters the chamber B from the reservoir D through a pipe 61*, which is normally open and permits a free passage for the fluid, which, flowing through the pipe, rises in the chamber B until the end of the gross of air to the reservoir is prevented, while it necessarily follows that the flow ceases. By this device the quantity of fluid in the chamber B does not vary, but remains substantially the same, being replenished as fast as it is used.

For the purpose of entirely cutting off the supply of carbureting fluid from the chamber B when necessary the pipe 01 is provided with a valve (1 an enlarged view of which is shown in Fig. 2, the construction therein shown bebelow the normalsurface of the fluid in the reting fluid and finally, having become thorpipe 0 is covered or sealed and further ining especially adapted .for use where the ap-' paratus is placed below the surface of the ground, as represented in the drawings.

In the construction shown the supply-pipe d is provided with a valve-casing for the valve 01 to which is attached a tube (1 which extends to within a short distance of the surface of the ground and is provided at its upper end with a sleeve d through which the valve-stem (1 passes. The opening in the sleeve andthe portion of the valve-stem passing through it are screw-threaded, so that by turning the valve -stem the valve may be raised or lowered at will. A second cap (i adapted to be placed upon or over the cap d, is provided, which may be removed for the purpose of operating the valve 01 the stem of which is adapted to be turned by akey or wrench applied to the part 01 The reservoir is provided with a supply-pipe g and a vent pipe g, which extend above the level of the ground and are closed by means of screwcaps. In order to prevent any displacement of the pipes in the act of removing the caps, I provide the pipes with a device shown in detail in Figs. 3 and 4, which consists of a lug H, having shoulders which are preferably square and an opening through which the pipe passes and in which it is secured by means of a set-screw h. This lug is placed upon the pipe at a point below the surface of the ground, where it comes in contact with the earth which is packed around it and pre= vents the pipe d from turning while the cap is being put on or removed. The vent-pipe g and the deliverypipe g of the carburetedair chamber of the carburetor may also be provided with this device, if desired.

By forming my machine, as described, with the inclosing casing forming a space surrounding the lateral and top walls of the carbureting-chamber it will be seen that if any leakage occurs from the carbureting-chamber the carbureted air will escape not into the air, but into said space which forms the carbureted air chamber, thereby preventing waste.

What I claim, and desire to secure by Letters Patent, is-- 1. In a device for carbureting air, the combination, with the inclosing casing, of a carbureting-chamber within said casing, so constructed as to leave a space between the two surrounding the carbureting-chamber and constituting the carbureted-air chamber, the

said carbureting-chamber having a liquidreceptacle, an air-chamber above said liquidreceptacle, having a series of outlets for discharging air within said liquid-receptacle, a hollow perforated disk for distributing the air, having outlet-passages discharging into the air-chamber, and means for supplying air to said air-distributing disk, substantially as described.

2. In a device for carburetingair, the combination, with the inclosing casing,of the carbureting-chamber within the same, so constructed as to leave a space between the two surrounding the carbureting-chamber and forming the carbureted-air chamber, said carbureting-chamber having aliquid-receptaole, an air-chamber above said liquid-receptacle, a series of discharge-pipes extending from said air-chamber to near the bottom of said liquid-receptacle, an air-distributing disk located within and having perforations dis charging into said air-chamber, an air-supply pipe connected with said air-distributin g disk,

and openings in said liquid-receptacle communieati ng with said carbureted-air chamber, substantially as described.

3. In a device for carbureting air, the com 'bination, with the carbureting-chamber, of a liquid-supply pipe for the same, located beneath the surface of the ground, a valve located in said pipe for controlling the liquidsupply, a valve-stem extending from said valve to a point adjacent to the surface of the ground, an inclosing casing for said valvestem provided with a closing'cap, and a construction secured to said casing to prevent removed to give access to the valve-stem, substantially as described. I

4. The combination of a carburetor adapted to be placed below the surface of the ground, a pipe leading thereto provided with a screw-threaded closing-cap, and a device for preventing the turning of said pipe, consistin g of a part constructed to rigidly engage said pipe, having laterally-extending portions for engaging the surrounding earth, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN CLINGMAN.
